The GLG Toolkit is an extremely flexible and robust graphical framework for building elaborate visual simulations and dynamic graphical screens that display real-time data.
The Embedded Edition of the Toolkit provides support for ARM processors and embedded boards. Both ARM6 and ARM7 architectures are supported, including the Beagle Bone and Raspberry Pi boards. The Embedded Edition supports all features of the Toolkit, making it easy to develop an application that can be run on both desktop and embedded devices.
The Free Community Edition of the GLG Toolkit is a fully functional version of the toolkit containing a complete set of tools for developing embedded graphics and elaborate HMI interfaces for embedded devices.
The Community Edition includes a graphical editor, a large number of pre-built components and a native C/C++ library for using the HMI screens into an application. The GIS component is also provided, as well as a Java class library for developing Java and Web applications. The Toolkit's run-time library can be easily integrated into existing applications, making it an ideal tool for developing embedded graphical interfaces.

The GLG Graphics
is an interactive graphical editor for creating animated graphical
drawings, elaborate simulations and HMI screens. Using
and define resources
for animating the drawing with real-time data.
The GLG drawings are screen resolution-independent, which makes it possible to deploy them on a wide range of displays - from large monitors to embedded LCD displays. Drawings created with the Builder can be reused between desktop and embedded applications. For convenience, the drawings are usually created on the development system on the desktop, but the Builder can also be run on the embedded board itself, if necessary.
available in the Graphics Builder for drag and drop editing via the
widget palettes. New widgets
and custom symbols may be
created with the Builder and added to the Builder's palettes as reusable components.
The Toolkit provides native C/C++ libraries for the run-time deployment. on a variety platforms, including ARM-based embedded devices and boards. An application can be developed on a desktop system and then compiled for the embedded ARM device. Both ARM6 and ARM7 architectures are supported, including the BeagleBone and Raspberry Pi boards.
The GLG library
is used by an
load, display and update the HMI screens with real-time data at run time. The library
provides a concise but extensive
programming API that allows developers to configure the HMI displays at
run time, as well as to handle user
interaction with the displays.
A Java version of the GLG library may be used to create a cross-platform version of an application that can also be deployed on the Web in a Web browser.
The GLG drawings can be reused between the C/C++ and Java versions of the application. The Java version of the GLG library provides the same functionality and a similar API as the C/C++ version, making it possible to reuse the programming logic and simplify porting an application from C/C++ to Java.
A JavaEE-based Graphics Server is also included and may be used for displaying GLG screens on mobile devices. The Graphics Server provides a thin-client server-side alternative for displaying dynamic graphics on a web page without the need for browser plugins or Java applets. With the Graphics Server, the graphics is generated on the web server using a Java Servlet and displayed in a browser using only the standard HTML and Java Script.
GLG Map Server library and an integrated GIS component are also available for embedded ARM devices, makes it possible to deploy a GIS application on a stand-alone embedded system.
When used with the Toolkit, an integrated GIS Object renders a map in the background of a GLG drawing and takes care of all chores of zooming, panning and coordinate conversion, while the Toolkit handles rendering of dynamic icons on top of the map and updating them in real time.
The GLG Graphics Builder facilitates interactive setup and rapid prototyping of the map component with no programming, by simply editing GIS objects in the drawing.
The GIS component supports optimized rendering of millions of points, both raster, vector and elevation data, rectangular and orthographic projections, unlimited layering, full alpha-blending, transparency and dynamic attribute thresholding. It is optimized for both the whole globe and small region maps, supports hierarchical tiling, tile cache and automatic layers selection based on zoom thresholds.
